The hotel has only two rooms and you will have a circular balcony with a 360 degree view, but in the afternoon it will be full of tourists. Since windows are not 100 percent darkened, you will be visible to them.

Therefore, the best option would be to walk through Rotterdam till 8-9 pm. From 22:10 to 9:30 the balcony will be yours. Nevertheless all the windows have curtains, if you need to be at the hotel during the day.

The cost of one night in this hotel is €400 (2016), you can book on booking.com. It's not cheap, but not expensive, given the unique experience. Choose a room with a view of the harbor, it is bigger. Do not forget to order breakfast in the room.
